Application led @ctober 7, 1.9522.

To all lwhom t may concern:

Be it known that l, Canne Basiivi, a citizen oi the United States. and a resident of Carteret7 in the co-unty'o l/liddlosex and State of New Jersey, have invented a new and lmproved lVindow Scaffold ot which the following is a full, clear, and exact descript-ion.

rllhis invention relates to scatlolds and particularly to an improved readily removable scaffold adapted for use in connection with windows.,

Another object ot the invention is to provide a scaffold particularly adapted for windows which may be set up and collapsed quickly and easily and readily adjusted to different size windows.

A further obj ect of the invention is to provide a removable scaffold for windows which may be applied and removed without injuringr the window or the scaffold.

ln the accompanying drawings- Figure l is a longitudinal vertical section through part of a window and through a scaiiiold embodying the invention.

Figure 2 is a perspective view of part of one end of the scall'old shown in Figure l.

Figure 3 is a horizontal sectional view through a window showing in top plan the scalitold illustrated in Figure l7 the section being taken through Figure l. approximately on line 3-3.

Figure d is an elevation ot the scaffold when folded.

Referring to the accoiupa-nylugA drawings by numeral, ll indicates the wall of a huilding and 12 the window trame, said trame being` provided with the usual bottoni jainbv 13, said jamb being adapted to receive the horizontal supporting` hars le and l5 which bars may be made oi any desired material., as it'or instance7 wood7 said bars at one end being' connected together hy an adjustable connecting structure lli. The structure lli is preferably made from two wood bars li' and 19 cut away at i9 and 2O respectively whereby they may eo-operate together as illustrated iu Figure An encirclingV strap 2l is secured to veach of the bars la7 and 18 near their reduced ends so that these bars niay be spread apart until the straps 2l engage and may be inoved towards each other until the respective ends 22 and 23 engage the `respective end sockets 24 and 25. :Pretto connect the structur 16 thereto.

erably, a reinforcing` Strap 2o is secured in any desired manner to the large end oit each or the bars l? and 18i said strap and said hars being provided with a plurality of.

apertures 2? -lojr receiving the respective sore vs or bolts land said screws or bolts extending into the horizontal bars ifi and The structure i6 acts as a stop for the horizontal bars @ist and l5 and. rests against the window frame l2 when the device is in use as indicated Figures l and 3.

Each of the bars il and l5 is provided with a vertical stando. l 30 and a diagonal brace 3l which are rigidly secured to the respective bars and are rigidly secured together at their lower ends by suitable fastening; means, as for instance, screws 32. Pret crab-ly, the brace 3l extends a short distance beyond the standard 30 so as to engage the wall 1l while the upper part of the standard 30 is engaging the jainb 13 and the bars land l5 are thereby held in a horizontal position. A suitable platform 33 may be mounted on the bars le and l5 loosely or may be secured thereto by bolts or yany other suitable securing` nie-ans. t u

t une outer end of each ol' the horizontal bars 14- and l5 there is provided an upright which is preferably formed ot angle iron7 said uprights being` pivotally connected in place by a suitable. pivotal bolt 35., A notch arranged in. the upper end oi the upright tlf/l (20-acting with the notch 37 of the rail 38. lt will he noted that the notch 3T is deejer than the notch 3S whereby the liange of the rail will overlap notch 56 and thereby become locked to the upright Se.

The rail $38 is preferably divided into two sections 39 and 40, said sections beingpreterably angle irons and adjustably locked together by reason ot the bolt Ull vFitted into section 4l() and extending througl'i the slot 4-2 in the section 35;). il link /l-Zs is pivotally connected with the upright dll: near the top, said linlr having a hook oud ifl; at one endU7 said hook end 4"' interlocking; with an eye screw which is screwed into the window traine l2, lt will he noted from Figure 3 that there are wo eye screws l5 tor supporting the respective links 43, which linlrs in turn are pivotally connected with the respective uprights 341. rlhe rail 38 connects these uprights whereby with this rail and the links 43 a fence or railing is provided so that the Workmen using the scaffold cannot readily :tall oii.

When it is desired to remove the scaffold, the links 43 are disconnected from the screw eyes 45 and rail 38 is disconnected from the uprights 34E. After this has been done, the uprights are folded as indicated in Figure Il and the horizontal bars 14; and 15 are also folded in a similar manner. The scr-ew yes 45 are left in place preferably so 'that in case it is desired to again use the scal'oid ou that particular Window, the)T will be in posi-tion for use. The scaliiold may be quickly and easily set up and removed and, consequently, may be used for cleaning the Windows or for painting the Window i'rarnes and sashes. By reason of the slot 42 and the adjustable feature oi the structure 16, the

I0 device may be used in narrow Windows or Wide Windows. It Will, of course, be evident that the boards forming the platform 33 must be or the desired width to rest on the bars lli and l5 though ordinarily these boards are provided long enough to rest on the 'bars 14: and 15 when the scaffold has been adjusted to its greatest Width.

vWhat l claim is:i

in a scaffold of the character described, a platform. means for supporting the platform, a step rail connected .with said supporting means, said stop rail being formed in two sections, said sections having reduced overiapping portions, a pair of straps Ylier guiding said overlapping portions, and telescopir y bars connected to the opposite ends o.. said platform supportingmeans for preventing the spreading of the saine.
